Description: | A subset of the radiation measurements had an incorrect gain applied to raw data in period from 20021218-20031218. To correct for this, a multiplicative correction factor of 1.11 were applied to raw data used for the following variables: r_down_short_hemisp r_down_long_hemisp r_up_short_hemisp r_up_long_hemisp Note that the long wave variables are computed by adding the black body thermal radiation from the radiometer body to each of the long wave signals. Hence, the multiplicative correction is applied to the raw long wave fluxes before adding in the flux from the radiometer body. |

The result was very very slick roads and mass power outages. The SGP central facility lost power at 8:55 PM CDT on Sunday, December 27th. The power was restored on 7:56 PM CDT on Wednesday, December 30th Site Emergency procedures were activated and Technicians drained water out of instrument reservoirs and other measures as needed, early Monday morning. On Wednesdays as roads and power started was restored to much of the areas east of I-35 , Site Technicians performed maintenance on several Extended Facilities. During this period, data are potentially missing, incorrect, or suspect. Carefully inspect the data before use. |

Subject: | SGP/MET/E39 - False tips in high winds |
DataStreams: | sgpmetE39.b1 |
Description: | The TBRG's were mounted at a height that made them prone to vibrations caused by high winds which may have caused false tips. The end date of this DQR indicates when the rain gauge was lowered to mitigate these effects. Effects on the total precipitation amounts are assumed to be negligible. |
